Connection of wiring

Connect the wires in accordance with the diagram of eachsystem.

All wiring must be performaed by an authorized electrician. All field supplied parts and materials and electric works must

conform to local codes. Use copper wire only

Connection of wiring

A circuit breker capable of shutting down power supply to theentire system must be installed.

A single switch can be used to supply power to units on thesame system. However, branch switches and branch circuitbreakers must be selected carefully.

Fit the power supply wiring of each unit with a switch and fuse asshown in the drawing.

Be sure to give the electric grounding (earth) connection.Complete system example

Specifications for field supplied fuses and wire

Precautions

1 Do not connect wires of different gauge to the same powersupply terminal. Looseness in the connection may causeoverheating.When connecting more than one wire to the power supplywiring, use a 2 mm2 (1.6) gauge wire.

2 Keep total current of crossover wiring between indoor units lessthan 12 A.When using two power wiring of a gauge greater than 2 mm2(1.6), branch the line outside the terminal board of the unit inaccordance with electrical equipment standards.The branch must be sheathed so as to provide an equal orgreater degree of insulation as the power supply wiring itself.

3 Do not connect wires of different gauge to the same groundingterminal. Looseness in the connection may deteriorateprotection.

4 Keep the power supply wiring distant from other wires to preventnoise.

5 For remote controller wiring, refer to the Installation manual ofthe remote controller..

PurposesWhen Combined with a local ventilating fan (such as the one in toiletand kitchen), the air flow rate of HRV is balanced by either fanoperation or exhaust operation.

However, a circuit with voltaged and low current (16 V, 10 mA) isfromed between the JC and J1, so a relay with low-load contact pointmust be used.

Functions

The unit performs overcharged operation to prevent back flow ofodor.
